An amateur looking job. Just by looking at the completed wall, you can see it's been done by someone who hasn't really got much of a clue. As Steve says, the thick coat corner bead that he fitted is nowhere near straight/plumb, (was it a thick coat bead)?. The render has been scratched far too deep, by the wrong type of tool, should have been a "scratch (devil) float", with a "small" nail protruding "just enough" to provide a key. The render/plaster should have finished lower, about a couple of inches from the floor level, (max), to give the skirting a good fixing/backing. The overall look of the job says a lot. A newly plastered wall should have a neat look about it, with nice regular sweeps of the trowel up the wall or across, depending on your choice. I always prefer to rub up/trowel up the way, others might prefer to go across.
By troweling here and there, runny cream ( not good), too much water when trowelling, trowel running in all directions, makes a job look patchy, dog rough.
I suppose it's a better job than you had done the last time, and it's not falling off,, but it's still very poor quality, especially for the amount you paid.
I hope by the time the skirtings on and it's all decorated, it'll look ok.
